It's interesting she used Thompson as the baby's last name -- which she didn't have to do. Also, the fact she says "our" in the post makes it seem like she's still in a relationship with Tristan ... despite all the cheating.

Kardashian sources say the name runs in the family. True was the name of Kris' grandfather, Khloe's great grandfather.

Khloe also broke the details of True's birth stats today, weighing in at 6 lbs, 13 oz when she was born.

It's Khloe and Tristan Thompson's first kid together. Tristan has a son from a previous relationship
